The Internet of Things (IoT) hardware landscape is evolving rapidly in 2025, with billions of connected devices enabling new capabilities across industries. Staying informed on the latest IoT hardware trends is crucial for engineers, product managers, and tech enthusiasts alike. IoT adoption continues to accelerate—forecasts project the IoT market will reach over $629 billion by 2025, and the number of connected IoT devices is expected to exceed 27 billion by 2025. This growth comes despite recent challenges (e.g. supply chain issues in 2024), and it’s driven by advancements in connectivity, edge computing, and AI.
In this context, five key hardware trends are shaping IoT development this year. Below we highlight the top 5 IoT hardware trends in 2025, backed by industry data and examples:
- Edge Computing Devices – Moving data processing to the device edge for faster, local analytics.
- Advances in 5G (and 6G) – Next-gen wireless standards enabling ultra-fast, low-latency IoT connectivity.
- On-Device AI/ML Integration – Embedding artificial intelligence and machine learning capabilities directly into IoT hardware.
- Low-Power, High-Efficiency Chipsets – New chip designs that deliver more performance per watt, extending battery life.
- Enhanced Security & Encryption – Stronger hardware-level security features to protect IoT endpoints from cyber
threats.
Let’s dive into each of these IoT hardware trends and why they matter in 2025.
Edge Computing Devices – IoT Hardware Trends 2025
One of the most important IoT hardware trends of 2025 is the rise of edge computing devices. Edge computing refers to processing data at or near the source (the “edge”) of the network rather than relying solely on cloud data centers. By performing computations on IoT devices or local gateways, edge computing dramatically reduces latency and bandwidth usage, enabling real-time responsiveness. This is critical for time-sensitive applications like autonomous vehicles, industrial automation, and remote healthcare, where even milliseconds matter.
Why Edge Computing Matters: With the explosion of IoT data, sending everything to the cloud has become impractical. In fact, Gartner predicts that by 2025, 75% of enterprise-generated data will be created and processed at the edge, up from just 10% in 2018. Local processing relieves network bottlenecks and avoids the “crushing” data loads that purely cloud-based systems would face. By 2025, organizations not adopting edge computing will risk crippling data bottlenecks that slow down real-time decision-making. Edge-capable hardware – from powerful IoT gateways to smarter sensors – is therefore taking center stage in IoT architecture.
Key benefits of edge computing in IoT hardware include:
- Ultra-Low Latency: Processing data on-device or on nearby edge servers enables immediate insights and control. This is essential for scenarios like robotics or smart grids that require split-second feedback. For example, edge analytics can guide an autonomous drone’s navigation in real time without cloud delay.
- Bandwidth & Cost Savings: Only processed or relevant data (rather than raw high-volume streams) is sent to the cloud, reducing bandwidth usage and cloud storage costs. One study notes that edge computing minimizes unnecessary data transmission, easing the load on centralized servers.
- Enhanced Privacy: Sensitive information can be analyzed locally instead of being transmitted externally. Keeping personal or confidential data at the edge (on the device or local network) lowers exposure and helps meet data sovereignty requirements.
Industry investments reflect this trend: the edge computing market is booming, projected to grow from about $36.5 billion in 2021 to $87.3 billion by 2026. Companies are deploying more capable edge hardware – such as on-premises micro data centers and AI-enabled IoT nodes – to handle the deluge of sensor data. In summary, edge computing devices are a leading IoT hardware trend because they empower faster, smarter, and more secure IoT operations by processing data where it’s collected.
5G and 6G Connectivity – IoT Hardware Trends 2025
Advances in wireless networking are another driving force in IoT hardware trends for 2025. In particular, 5G networks – and the early glimmers of 6G on the horizon – are transforming what IoT devices can do.
5G Boosts IoT: The global rollout of 5G is enabling ultra-fast speeds, massive device capacity, and millisecond-level latency for wireless IoT connections. This is unlocking “hyperconnectivity” for IoT deployments. By 2025, 5G coverage is expected to reach 65% of the world’s population (with 2.6 billion 5G subscriptions), and billions of IoT devices are coming online with cellular connectivity. Ericsson forecasts that IoT connections over cellular networks will approach 7 billion by 2025, fueled largely by 5G growth.
Importantly for IoT hardware, 5G introduces features like network slicing, which allows dedicated virtual networks tailored to specific IoT use cases (for example, a slice optimized for low-latency healthcare sensors). Another 5G advancement is RedCap (Reduced Capability), a new device category in 5G that provides reliable broadband IoT connectivity with lower complexity and power consumption. RedCap is ideal for wearables, industrial sensors and smart meters – IoT devices that don’t need full 5G speed but benefit from its efficiency and range. These innovations mean IoT hardware in 2025 can connect more flexibly: high-bandwidth gadgets can leverage full 5G, while power-constrained devices use 5G variants or fallback to LTE/LPWAN as needed.
Meanwhile, Wi-Fi 6/6E and Wi-Fi 7 are advancing on the local networking front, offering higher throughput and lower latency for smart homes and offices. Low-Power Wide Area Networks (LPWANs) like LoRaWAN, Sigfox, and NB-IoT also continue to complement 5G by connecting ultra-low-power sensors over long ranges. The trend in 2025 is toward hybrid connectivity – IoT solutions combining 5G, Wi-Fi, LPWAN, and even satellite links to ensure ubiquitous coverage. For instance, IoT devices in remote areas can switch to satellite or high-altitude networks when out of cell range. The new GSMA eSIM standard (SGP.32), launching in 2025, will even allow IoT devices to seamlessly swap between carriers and network types for optimal signal and cost.
Looking ahead to 6G: While 5G is still being fully realized, the tech industry is already exploring 6G capabilities. 6G is not expected to roll out until around 2030, but research and early standardization are kicking off in 2025. The hope for 6G is to create an intelligent, ultra-low-latency network that can support unprecedented device density and new use cases like haptic internet and advanced automation. For IoT hardware, 6G could eventually mean embedded devices with even faster connectivity, sensing capabilities (6G may integrate sensing/radar features), and AI-optimized network handling. In the near term, though, the focus is on maximizing 5G’s potential. As one industry expert noted, fully leveraging 5G’s coverage and reliability is the prerequisite before 6G becomes a reality.
IoT hardware trends in connectivity are all about more speed, reliability, and reach: devices in 2025 are coming equipped with multi-band 5G modems, dual Wi-Fi6/5G radios, eSIMs, and other tech to stay connected everywhere. If you’re developing IoT products, ensuring compatibility with the latest wireless standards (and planning for future 6G upgrades) will be key.

AI and Machine Learning Integration – IoT Hardware Trends 2025
AI is everywhere in 2025 – including inside IoT devices themselves. The convergence of Artificial Intelligence and IoT (AIoT) is a major IoT hardware trend enabling smarter, more autonomous devices. Rather than sending data to a cloud AI service, many IoT endpoints now incorporate on-device machine learning processors or accelerators. This means an IoT sensor can “think” locally, analyzing data in real time and even making decisions using AI algorithms.
Industry leaders have observed that AI has become the new buzzword, even overtaking “IoT” in discussions of digital transformation. But it’s the combination of the two – AI + IoT = AIoT – that unlocks powerful new capabilities. By embedding ML models into hardware, IoT devices can perform tasks like image recognition, anomaly detection, predictive maintenance, and natural language processing without constant cloud help. For example, a smart factory sensor with an AI chip can detect equipment wear or predict failures on the spot, preventing downtime. (According to McKinsey, AI-driven IoT predictive maintenance could reduce maintenance costs by 10–40% and cut equipment downtime by up to 50% – a huge efficiency boost.) In smart cities, cameras and traffic lights equipped with AI can analyze traffic flow and adjust in real-time to reduce congestion and emissions. These kinds of intelligent behaviors are made possible by advances in IoT hardware.
Several developments are fueling this trend in 2025:
- Edge AI Chips: Semiconductor companies are producing specialized AI/ML chipsets for IoT devices that deliver high performance while minimizing energy consumption. These range from tiny microcontrollers with built-in neural network accelerators, to more powerful system-on-chips (SoCs) that can run computer vision or deep learning tasks at the edge. MediaTek, for instance, notes that chips are “smaller than ever” yet can handle intense AI workloads efficiently. Examples include Google’s Coral AI Edge TPU, NVIDIA’s Jetson line for IoT, and new AI-focused microcontrollers from companies like NXP and STMicroelectronics.
- TinyML and On-Device Models: There’s a growing ecosystem of lightweight machine learning frameworks (e.g. TensorFlow Lite for Microcontrollers, TinyML) enabling even resource-constrained IoT devices to run ML models. In 2025 we see smart wearables that can do heart rhythm analysis with onboard AI, security cameras that recognize threats locally, and voice assistants running on a chip in your light switch. Smart sensors now analyze data in real-time on the device, reducing the need to send everything to the cloud. This speeds up responses and improves reliability for use cases like retail analytics or home automation.
- Growth of AIoT Market: The strong business case for AI-integrated IoT is driving market growth. The global AIoT market (products and solutions combining AI and IoT) is valued around $10 billion in 2024 and is projected to grow to $13+ billion in 2025 (≈33% annual growth). Analysts attribute this growth to the proliferation of IoT data and the need for AI to derive value from it. In other words, as IoT networks expand, companies are investing in hardware that can intelligently manage and interpret the data deluge.
Overall, AI and ML integration into IoT hardware is making devices more autonomous and efficient. This trend also ties back to edge computing and connectivity – since on-device AI reduces dependency on cloud bandwidth and can operate even with limited connectivity. We expect AI capabilities to become a standard feature of new IoT hardware platforms. From consumer gadgets with built-in voice/image recognition to industrial machines with AI co-processors, the line between an “IoT device” and an “AI device” is blurring in 2025. Engineers should consider how leveraging on-board AI (or at least AI-ready hardware) can add value to their IoT products.
Low-Power, High-Efficiency Chipsets – IoT Hardware Trends 2025
IoT hardware is also being transformed at the component level by new chip designs that prioritize power efficiency. In 2025, there is a strong push for IoT chipsets that deliver more computing power while consuming minimal energy – crucial for battery-powered sensors and wearables that may need to run for years on a charge. Additionally, these chipsets are integrating more functions (processing, memory, wireless radios, AI accelerators) into single inexpensive packages, which lowers costs and device size.
Smarter and cheaper microcontrollers: A wave of next-generation microcontrollers (MCUs) and system-on-chip modules for IoT has hit the market. These include chips like Espressif’s ESP32 series, the Raspberry Pi Pico (RP2040), Nordic Semiconductor’s nRF54 series, and many others. Such chips pack substantial computing power, built-in wireless connectivity (Wi-Fi, Bluetooth, etc.), and improved energy efficiency – all at a lower price point than previous generations. The result is that advanced IoT capabilities (like connecting to the cloud, running AI algorithms, multitasking sensors) are now accessible even in low-cost devices. In 2025, a developer can purchase a few-dollar chip that supports dual-core processing, Bluetooth Low Energy, and sensor fusion, without draining a battery quickly. This democratization of high-performance hardware is accelerating IoT adoption across industries.
Ultra-low power design: Beyond raw performance, chipmakers are innovating to extend battery life. Techniques include using smaller transistor processes, ultra-low-power standby modes, energy-harvesting support, and specialized low-power wireless standards. Thanks to these improvements, many IoT sensors can operate for 5–10+ years on a single battery in the field. For example, newer Bluetooth LE chips and NB-IoT modems are designed to sip microamps of power in sleep mode, waking only to transmit as needed. Lower power consumption and longer battery life were explicitly highlighted as key hardware goals in 2025. This benefits deployments like agricultural sensors, asset trackers, or implanted medical devices where changing batteries is difficult or expensive.
Open-source architectures (RISC-V): Another notable trend is the rise of RISC-V architecture in IoT. RISC-V is an open-source CPU instruction set that companies can use to design custom processors without paying licensing fees (unlike traditional proprietary ARM cores). In 2025, more IoT chip manufacturers and even startups are adopting RISC-V to build specialized chips tailored to their needs. This is leading to more innovation and potentially lower-cost chips, since developers aren’t locked into one vendor’s IP. RISC-V based microcontrollers and secure elements are appearing in IoT devices, offering comparable performance to ARM Cortex-M series with greater flexibility for customization. The trend underscores a broader movement toward open hardware ecosystems in IoT, which can accelerate development and reduce costs for new products.
To summarize, new low-power, high-efficiency chipsets are a foundational IoT hardware trend enabling the other advances on this list. These chips provide the computing “brains” and connectivity of IoT devices, so improvements at the chip level ripple out to everything from smart home gadgets to industrial sensors. In 2025, expect IoT hardware to feature chips that are faster, cheaper, and greener: devices will have more processing muscle and AI capabilities, even as their energy consumption drops. For product designers, it’s a great opportunity to build IoT solutions that are both powerful and battery-friendly, leveraging the latest silicon innovations (and yes, Jaycon’s engineering team closely tracks these developments to integrate the best chipsets in our clients’ projects).
Enhanced Security and Encryption – IoT Hardware Trends 2025
With the proliferation of IoT devices, security has become paramount – making advanced security features one of the top IoT hardware trends in 2025. The more devices we connect (in homes, factories, cities), the more targets there are for cyberattacks. Unfortunately, attackers have noticed: IoT-targeted cyber attacks surged 400% in 2022 alone, and this upward trend is expected to continue into 2025. High-profile incidents – from hacked security cameras to compromised industrial sensors – have raised alarms about IoT vulnerabilities. In response, the industry is doubling down on hardware-level security measures to protect IoT endpoints.
Stronger encryption & device authentication: By 2025, IoT devices are increasingly built with encryption protocols and authentication mechanisms baked in. Data transmitted between IoT endpoints and the cloud is now routinely encrypted (e.g. via TLS/SSL) to prevent eavesdropping. Many devices also employ mutual authentication – ensuring a sensor only talks to an authorized server and vice versa, using cryptographic keys or certificates. Multi-factor authentication is being used for higher-level IoT systems access. In short, trust is becoming a first-class design parameter for IoT hardware and networks. As noted in one IoT trends report, IoT security in 2025 focuses on stronger encryption protocols, authentication, and even emerging tech like blockchain for device communications.
Hardware-based security (root of trust): A critical development is the use of dedicated security hardware within IoT devices. Manufacturers are adding secure elements or secure enclaves – essentially tamper-resistant chips – that store secret keys, handle encryption/decryption, and ensure the device boot firmware is authentic (secure boot). These hardware security modules create a “root of trust” in the device that software alone cannot easily compromise. In fact, experts predict that as AI increases the risk of cracking software encryption, IoT devices will have “no other choice than to use secure elements or secure MCUs” to safeguard cryptographic operations. We’re seeing this in practice: many modern IoT processors (e.g. ARM Cortex-M TrustZone, or chips with TPM-like modules) now include isolated security subsystems. This trend greatly raises the bar for hackers – breaking into the device requires physical attacks or defeating strong cryptographic silicon, not just guessing a default password.
Global IoT security standards: 2025 is also a year where regulatory and standards initiatives kick in to improve IoT security across the board. Governments in multiple regions have introduced baseline security requirements for IoT devices. For example, the U.K. became the first country to mandate IoT cybersecurity standards by law (such as unique device passwords and vulnerability disclosure policies). The European Union is implementing rules that any products sold meet minimum cybersecurity criteria, and the U.S. has launched a voluntary IoT security labeling program to inform consumers. All these moves push IoT hardware makers to build better security into devices from the start, or else face market exclusion. Industry consortia are also updating technical standards (for instance, new guidelines for post-quantum cryptography to future-proof IoT encryption, and Zero Trust architectures that assume no device or network can be inherently trusted). The big picture: security is now a core feature of IoT hardware, not an afterthought.
Some key security features trending in IoT hardware include:
- Secure Boot & Firmware Update: IoT devices now often implement secure boot processes (the device verifies its software signature at startup) and encrypted firmware updates to prevent malicious code injection.
- End-to-End Encryption: Data at rest on the device and in transit across networks is protected using robust encryption (AES-256, RSA/ECC, etc.), sometimes accelerated by onboard cryptographic co-processors for efficiency.
- Device Identity & PKI: Each device can have a unique cryptographic identity (e.g. an embedded certificate or key burned in at manufacture). Public-key infrastructures (PKI) and blockchain-based ledgers are used to manage these identities and ensure only trusted devices join the network.
- AI-Powered Security Monitoring: Just as AI helps devices function, it also helps secure them. Machine learning is being used in IoT routers and platforms to detect anomalous device behavior (intrusion detection) and automatically quarantine or shut down compromised nodes.
By implementing these measures, companies aim to significantly reduce the risk of IoT breaches that could compromise data or even physical safety. After all, an insecure IoT device can be a gateway into a corporate network or a means to disrupt critical infrastructure. The IoT hardware trend toward enhanced security is all about making connected devices resilient by design. For anyone developing or deploying IoT in 2025, investing in robust security – from encryption chips to strict authentication – is not optional, it’s essential. As the saying goes, the best way to enjoy the benefits of IoT is by securing it; the industry clearly recognizes this and is building the tools to do so.
